ABSTRACT:
A method is disclosed for measuring the remaining useful life of a hydrocarbon oil containing at least one additive species. An oil sample is mixed with a solvent, a solid substrate, and in some cases an electrolyte to produce an analysis sample. The analysis sample is placed into an electrolytic cell and subjected to a voltammetric analysis, whereby increasing potential is applied to the cell to produce an oxidation reaction and a varying electric current. The current during the voltammetric analysis is measured and recorded. Remaining useful life for the oil is then determined from the oxidation current wave height produced.
